I am currently working on my final year dissertation and most of it is done on LPS. I am using Cartosat-1 and ALOS PRISM imagery to create DTMs for an area that is located on a peninsula. The problem ...

I have a problem with calculating vegetation indices like EVI, GSAVI, SAVI on Landsat 7 images after I done a Brovey Transform, Modified Resolution Merge and HCS transformation in Erdas 2013. My study ...

I am trying to use MODIS satellite imagery to detect and track icebergs surrounding Antarctica. The software that I am using is Erdas Imagine 2014.
I am struggling to differentiate clouds from snow ...

I have created a NDVI image from Landsat 7 data using ERDAS (veg_NDVI.gmd). This model was already in ERDAS 9.3. After creation the final output visually highlighting vegetative areas but the value ...

I am working on Land Use/Land Cover Classification of the Hindon river(India) watershed extracted using Aster DEM. Landsat 8 scenes had been used and mosaicked for the required AOI using the Watershed ...

I'm trying to do a fuzzy land cover classification using maximum likelihood classification. I need to get the probability of each pixel to fall in a particular class. Some equations have been formed ...

I downloaded the surface reflectance landsat 5 scenes but when I layer stacked them my image was not how I imagined. I manually used atcor on normal scenes and it looks nothing like the scenes I layer ...

New to Erdas but I have to do a project and I have chosen to do a landcover land change detection. I have two Landsat 5 images, five years apart from each other. My question is: what is my next step?
...

I am trying to do Mosaic in Erdas imagine. I have three tiles of Landsat data: one is Sept89 others two are March90. I am using Weighted Seamline method and Histogram Matching for the mosaicing but ...

I´m using Erdas Imagine 2010 and need to process images to get reflectance values using the Empirical Line method. To achieve this I need to process 200+ images, each containing multiple bands, with a ...

I have 12 MODIS images (one of each month). I want to create a single image having maximum annual pixel values for each pixel. I did layer stacking operation in Erdas Imagine 13, but how to extract ...

When creating orthos in Erdas imagine or LPS from geoeye-1 (or other) satellite images having _rpc.txt files, which are referenced in WGS84 generally, what should be the projection of the used DEM? If ...

I have a LULC for India. i need to filter out non-agricultural, non-builtup, non-waterbody, non-forest. simply wastelands,scrubs,swamps, grasslands etc.
Please how to filter these using ERDAS IMAGINE ...

I've just run a principal components analysis on a Landsat image and am trying to calculate my factor loadings. I'm using the textbook Digital Image Processing by John Jenson as a guide and it says ...

I pan-sharpened one Landsat Image on ERDAS using the resolution merge resource, with brovey transform and nearest neighbor techniques. But I was told that in terms of land-use classification, it would ...

After a supervised classification in ERDAS IMAGINE I have some undefined "ghost classes" in the attribute table. Also have a look at this youtube video at about 7:12.
I'm wondering why they arise and ...

I performed radiometric correction analysis on Landsat 8 image ( format: integer unsigned 16 bit) in ERDAS IMAGIN 2014.
However, the output image would be created if I could select format: float 32 ...

I am trying to open a .img image fil in ERDAS Imagine and I keep getting the message "End of file reading dictionary" with ERDAS not responding. The program gets stuck here and I have to shut it down. ...

I have some issues with orthoresampling images in ERDAS Photogrammetry (formerly LPS). I've set up two different image blocks (including orientation and camera paramters) and created multiple digital ...
